Experimental Studies of Polyarmored Fiber Concrete
Incoming article date: 04.08.2025Within the framework of this article, experimental studies of concrete reinforced with polypropylene fiber of two geometric dimensions of 6 mm and 12 mm are presented. Studies were carried out on samples of cubes 10 × 10 × 10 cm and samples of prisms 10 × 10 × 40 cm. In total, more than 100 samples were tested. The objectives of the experimental study: testing fiber concrete samples for compression, analyzing the results obtained, identifying changes in strength and deformation characteristics as a result of fiber reinforcement. Tests of the samples showed an increase in strength of up to 20%, as well as the effect of the percentage of fiber reinforcement on strength properties. The limit percentage of fiber reinforcement was determined, when exceeding which a decrease in strength properties occurs
